CVE-2025-42902 (GCVE-0-2025-42902)

Vulnerability from cvelistv5 – Published: 2025-10-14 00:17 – Updated: 2025-10-14 15:22

Title

Memory Corruption vulnerability in SAP Netweaver AS ABAP and ABAP Platform

Summary

Due to the memory corruption vulnerability in SAP NetWeaver AS ABAP and ABAP Platform, an unauthenticated attacker can send a corrupted SAP Logon Ticket or SAP Assertion Ticket to the SAP application server. This leads to a dereference of NULL which makes the work process crash. As a result, it has a low impact on the availability but no impact on the confidentiality and integrity.

Severity

5.3 (Medium)

CVE-2025-40779 (GCVE-0-2025-40779)

Vulnerability from cvelistv5 – Published: 2025-08-27 20:23 – Updated: 2025-11-04 21:10

Title

Kea crash upon interaction between specific client options and subnet selection

Summary

If a DHCPv4 client sends a request with some specific options, and Kea fails to find an appropriate subnet for the client, the `kea-dhcp4` process will abort with an assertion failure. This happens only if the client request is unicast directly to Kea; broadcast messages do not cause the problem. This issue affects Kea versions 2.7.1 through 2.7.9, 3.0.0, and 3.1.0.

Severity

7.5 (High)

Mitigation MIT-56

Implementation

For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].

Mitigation

Requirements

Select a programming language that is not susceptible to these issues.

Mitigation

Implementation

Check the results of all functions that return a value and verify that the value is non-null before acting upon it.

Mitigation

Architecture and Design

Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.

Mitigation

Implementation

Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
